Hi @Tone  The ellipseGeodesic method is very fussy about its parameters.  You need to make sure you set them all and you also need to pass in a center point which has a known spatial reference. I've created an example ellipse method which should help you:     private Polygon makeEllipse() { // create parameters and set all the parameters GeodesicEllipseParameters parameters = new GeodesicEllipseParameters(); parameters.setCenter(new Point(3,14, SpatialReferences.getWebMercator())); // Note the spatial reference parameters.setGeometryType(GeometryType.POLYGON); parameters.setSemiAxis1Length(100); parameters.setSemiAxis2Length(200); parameters.setAxisDirection(45); parameters.setMaxPointCount(100); parameters.setAngularUnit(new AngularUnit(AngularUnitId.DEGREES)); parameters.setLinearUnit(new LinearUnit(LinearUnitId.METERS)); parameters.setMaxSegmentLength(20); Polygon ellipsePoly = (Polygon) GeometryEngine.ellipseGeodesic(parameters); return ellipsePoly; }       This is how I used the resulting geometry:     SimpleLineSymbol lineSymbol = new SimpleLineSymbol(SimpleLineSymbol.Style.SOLID, 0xFF0063FF, 1); SimpleFillSymbol fillSymbol = new SimpleFillSymbol(SimpleFillSymbol.Style.SOLID, 0xFF00FF00, lineSymbol); Graphic graphic = new Graphic(makeEllipse(), fillSymbol); graphicsOverlay.getGraphics().add(graphic);     Looks like this:   Let me know if this helps Mark ...

If you are wanting to draw a polygon with a hole in it, the following method shows how this can be achieved.  The polygon is made up of "parts" which form the inner and out rings of your polygon with a hole it it.   private Polygon makePolygonWithHole() { // create a new point collection for polygon PointCollection outerPoints = new PointCollection(SpatialReferences.getWebMercator()); // create and add points to the point collection outerPoints.add(new Point(2000, 2000)); outerPoints.add(new Point(2000, 4000)); outerPoints.add(new Point(4000, 4000)); outerPoints.add(new Point(4000, 2000)); Part outerPart = new Part(outerPoints); // inner part (the hole) PointCollection innerPoints = new PointCollection(SpatialReferences.getWebMercator()); innerPoints.add(new Point(3500,2500)); innerPoints.add(new Point(3500,3500)); innerPoints.add(new Point(2500,3500)); innerPoints.add(new Point(2500,2500)); Part innerPart = new Part(innerPoints); // make parts for multi part polygon PartCollection partCollection = new PartCollection(SpatialReferences.getWebMercator()); partCollection.add(outerPart); partCollection.add(innerPart); // create the polyline from the point collection Polygon polygon = new Polygon(partCollection); return (Polygon) GeometryEngine.simplify(polygon); }     The polygon can be used in features (persisted in a feature service for example), or a graphics overlay.  I've shown some simple code below which shows how to draw the polygon in a graphics overlay:   // create a map view and set the map to it mapView = new MapView(); mapView.setMap(map); GraphicsOverlay graphicsOverlay = new GraphicsOverlay(); mapView.getGraphicsOverlays().add(graphicsOverlay); SimpleLineSymbol lineSymbol = new SimpleLineSymbol(SimpleLineSymbol.Style.SOLID, 0xFF0063FF, 1); SimpleFillSymbol fillSymbol = new SimpleFillSymbol(SimpleFillSymbol.Style.SOLID, 0xFF00FF00, lineSymbol); Graphic graphicWithHole = new Graphic(makePolygonWithHole(), fillSymbol); graphicsOverlay.getGraphics().add(graphicWithHole);         Multi part polygons can also be created with parts.

The default mode for a query operation is to limit the attributes returned so things render quicker and you are transferring less data across the network.  It is explained here. In the code when you perform a query to get the features you can set it so you return everything.  Here is some very crude code to show it:   // define the feature table ServiceFeatureTable featureTable = new ServiceFeatureTable("https://sampleserver6.arcgisonline.com/arcgis/rest/services/DamageAssessment/FeatureServer/0"); featureTable.loadAsync(); // load it and wait... featureTable.addDoneLoadingListener(() -> { System.out.println("load status " + featureTable.getLoadStatus()); // query parameters for everything QueryParameters queryParameters = new QueryParameters(); queryParameters.setWhereClause("1=1"); // query the table //ListenableFuture<FeatureQueryResult> future = featureTable.queryFeaturesAsync(queryParameters); // returns default fields only ListenableFuture<FeatureQueryResult> future = featureTable.queryFeaturesAsync(queryParameters, ServiceFeatureTable.QueryFeatureFields.LOAD_ALL); try { // thread blocks here until results come back FeatureQueryResult queryResult = future.get(); // take a look at the features we've got for (Feature feature : queryResult) { System.out.println(" attr " + feature.getAttributes().keySet()); } } catch (InterruptedException e) { e.printStackTrace(); } catch (ExecutionException e) { e.printStackTrace(); } });   You mention that you are writing an app which does not use JavaFX controls.  Can you tell me how you are using the SDK?   ...

I can see the problem here, the rendering mode for a GraphicsOverlay is set when you instantiate it.  The default constructor will set it in DYNAMIC, but there is an overload which allows you to set this yourself. The code you've written for changing the rendering mode is for feature layers. Using the following code, I've managed to render your arrowhead: PointCollection polylinePoints = new PointCollection(SpatialReferences.getWgs84()); polylinePoints.add(new Point(10, 10)); polylinePoints.add(new Point(20, 20)); Polyline polyline = new Polyline(polylinePoints); SimpleLineSymbol lineSymbol = new SimpleLineSymbol(SimpleLineSymbol.Style.SOLID, 0xFF0063FF, 7, SimpleLineSymbol.MarkerStyle.ARROW, SimpleLineSymbol.MarkerPlacement.END); Graphic polylineGraphic = new Graphic(polyline, lineSymbol); GraphicsOverlay graphicsOverlay = new GraphicsOverlay(GraphicsOverlay.RenderingMode.STATIC); sceneView.getGraphicsOverlays().add(graphicsOverlay); graphicsOverlay.getGraphics().add(polylineGraphic); I am however going to look at  making the arrow head to render in the dynamic rendering mode for a future release. Does this help?   ... View more

@HammadMuddassir 10.2.4 of ArcGIS Runtime is a very old release and no longer supported.  It sounds like you are migrating an app from Map Objects, so replacing it with another outdated product isn't recommended. You need to be using the latest version which is 100.12.0.   I really would step back and look at your workflows and see if you can modernise them.  Although we do support direct connect to SDE databases via Local Server, there will be a license cost implication to using this.  It is likely to be more cost effective to access your data using an ArcGIS Server instance and there are several other benefits to using this as I've detailed in an earlier post. ...
